:Speciiflcation of Letters Patent. .Patent d.,Ap 29 1919.

To all whvmit-may concern Be itrknownithat I, EDWARD 3W. BURGESS, a citizen of the United States, residing at Chicago, inthe county of Cook and "State of Illinois, have .invented certain new nnd useful Improvements in :Power-T-ransrnission Gearing, of iwhichlhe followingis a full, clan, and exact specification.

My invention relates {to power transmission gearing fortractors EllICl'FfOl" use in propelling -l1-a-rvesters, -mowers, manure spreaders and other traetive driven implements, and transmitting motion to their operative parts from the tractor motor, '=whether the tractor :be moving or I stationaryythembject of the invention being :to provide .a .gear mechanism adapted :for substantially -=universal use in transmitting motion to the various farm implements :as indicated, or others, as circumstances require, .and to widen thera-nge'of usefulness ofthe-tractor and, make it an available power .=f0r many purposes. v

This object is. atteinedby means-of-meehnnism illustrated in the accompanying drawings, in whieh- Figure 1 is a side-elevation of a tractor having my invention embodied in its construction Fig. 2 is avertioal cross section on an enlarged scale of part of the po\ver;transmitting gearing; and

Fig. 3 .is a. detached detail of theitractor on an enlarged scale, as shown .in Fig. 1.

Referring ,to the drawings, wherein the same reference numerals designate like parts throughout the several views, the 'in ternal combustion engine, 1 including cylinder ,1, crank shaft ;2, and -fiy wheel 3, is

-mounted upon a truck having frame memsecured :to -one arm :11 of =2, ithreeermed spider having its arms radiating :from n hub 12, whereby it .is secured to one end of e sleeve -13 that is journnled upon the crank shaft 2 atoneiend of thepinion 8, and 1% represents a driving sprocket integral with the body of'thesleeve. 15 representsadisk like carrier having a hub 16 whereby it 'is ournaled :upon the crankshaft at the-op positeendmf the jp'inion 8. =17 represents one of asecu-red ito thecarrier, end 18 a rotatable gear Journaled upon the- -stud end =meshing with the pinion 8. 19 "represents n 'wheel having a hub -20 whereby-it is secured to thehub 16 by=means of a, key' QL-and aitraotion run :22. -23 represents :aitwo -pert casing havlng one Apart 2; provided with e hub 25 whereby it -is journ91led upon -'the hub 12, a. friction rim--26 and-e gear ring 27 secured 1 to %he :rim and meshing with 'the gear: 9, and 11 peripheral flange 28 whereby the part of the casing-is secured :by means of Ebolts .29 to in --second part :30 having e corresponding peripheral flange 31 a-n'd ahub :member :32 whereby it :is jonrnaled upon the=hub=20 of the wheel 1 9. 'A'gear ring 33 is carried by the-arms 151 andmeshes with the gears 181m0l1nted upon I the-"carrier 15. 34 represents a :frictionband :meohenism adapted to operetively engage :with the .friotion vrims 22-.und:26 and montrolled byitheloperator'myimeausofIhn-nd levels 35. Motion is :tmnsmitted to theztraction wheels y :means inf-B. chain :36 'engeging the driving sprocket l4 and-n driven sprocket :37 carried by the :tractor axle. The ,power transmission :mechanism as "described 1 above is .a common form of v,direct and reverse planetary gear.

My invention comprises means :for itrans mitting motion from such mechanism zto a countershnft :journaled in thee-flingsmarried by thBt1l1Gk=.fI-3II16 and .clisposedi nrallel with the engine.=slmift,:suoh znieans being operative whether the tractor xis removing or stationary, and includes a gear iring-38x-se cured-totheainner end:.ofz.thel-sprocket cmying sleeve 13, woollen-3.9 :being :mounted on the sleeve :between :the gear ring and the en ine frame, n-gear =40-secured-3to the huh-25 oftheeasin-g part-24ewou1rtershaft 41 having :its opposite tends jonmnled in outside and =inside bearing-boxes A2 and :43, respectively, that are secured ito ;-n .s plemental zfra-me member 44 and one -o 'rthe truck frame-members-d,lrespmtively,. wgeer Wheel 45 journaled upon :themounterslmft adjncentzthe bearing ,member43, an intermediate pinion 46 .journaled upon a bracket member 47 secured=to .the-truok-fmme 4 and series '01 preferably :three studs wheel forming part of the tractor brake- ,tcnsion'of the tractor axle.

nally disposed shaft 59 is journaled in.bear-' ings carried by the bar and secured-to-its.

meshing with a gear'ring 3'8 and gear wheel 15, and a gear wheel 48 journaled upon the conntershaft and meshing with the gear ring secured to the part 24 of the casing 23. The opposing ends of the hubs of the gear wheels and 48 are provided with clutch teeth 4-9, and 50 represents a clutch sleeve secured to the' eountersh'aft by means of a spline 51 and having clutch teethat-its opposite ends that may selectively engage with the clutch teeth upon the hubsof the gear wheels 4'5 and 48. 52 represents a clutch shipping fork in engagement with the sleeve that-may be controlled by theoperator in ,any proper manner,- as by a control member 52*. 53 represents a beveled pinion secured to the countershaft adjacent the opposite end of the bearing box. 42. A reduced part 54 of the countershaft extends beyond the pinion, and pivotally .-mounted thereon; is an arm 55 integral with a bearing box 56 secured to the front end of a bar 57, the rear end of the barbeing. supported by a bracket member 58 j ournaled upon an ex- A longitudifront end'is a pinion-6O that meshes with the pinion 58 and its rearend carries coupling members 61 whereby it maybe operatively-connected with other implements, as

desired. 62 represents a brake;:opera-ting mechanismwhereby the tractor may be held stationary; y

In operation, with the engine running idle, the crank shaft transmits motion through the pinion 8 to the orbital gear wheels 9 and-18, then tothe casing 23 through the orbital goals 9 and the gear' ring 27, and through the gear ring 3-3 and gear wheels 18 to'the'carrier 15 and wheel 19. When the casing is held againstrotw 'tionby means of the friction band mechanism, the orbital gear wheels 9 engaging with the gear ring 2'7, and armsll will be carried around the axis'of the engine crank shaft, thereby. rotating the sleeve 13 in a forwarddirection and the gear wheel 45 on the countershaft through the intermediate pinion -16 and gear rin 38 in the same direction, and the trac or moves forward driven by the sprocket chain. If the friction band mechanism is caused to hold the wheel 19 against rotation, the orbital gear wheels 18 will turn the gear ring 33 about anism, the sprocket wheel 14 holds the sleeve 13 and arms 11" against rotation and the orbital gears 9 through the gear ring 27 will impart rotative movement to the casing 23 'about the axis of the crankshaft, and the When the tractor is held stationary 'by means of the brake mechgear 10 rotates the gear wheel 48 while the tractor is held stationary and the counter shaft becomes available for transmitting a relatively slow speed to any stationary machine as desired.

Having shown and described one embodiment of my invention, I do not wish that it be confined to the specific details of the tractor as illustrated, it being understood that changes may be made in the form and proportion of its parts without departing from the spirit of the invention.
